Re: Indexing nonstandard geo_point field.
Hey,
you could index this as a geo shape (as this is valid GeoJSON). If you
really need the functionality for a geo_point, you need to change the
structure of the data.

This is what the JSON element looks like:
geo: {
type: Point,
coordinates: [
38.673459,
-77.336781

}
Is there anyway I could have elasticsearch reorder this array or convert
this field to a string without having to modify the source document prior
to indexing? Could this be done using a field mapping or script in
elasticsearch?

Re: Indexing nonstandard geo_point field.
I looked at the documenation for elasticsearch's geo_shape and it looks
like that use [longitude, latitude]
Found this node on the geo_shape documentation page
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-shape-type.html
Note: In GeoJSON, and therefore Elasticsearch, the correct*coordinate order
is longitude, latitude (X, Y)* within coordinate arrays. This differs from
many Geospatial APIs (e.g., Google Maps) that generally use the colloquial
latitude, longitude (Y, X).
An alternative I found was to use the computed fields plugin
https://github.com/SkillPages/elasticsearch-computed-fields
and create a mapping like this:
@coordinates-str : {
type : computed,
script : _source.geo.coordinates[0] + ',' +
_source.geo.coordinates[1],
result : {
type : geo_point,
store : true
}
}
This seems to create the string in the correct format for the geo point.
The issue I am having with this method right now is that Elasticsearch
will return an error if the source document does not have the
geo.coordinates field.

Indexing nonstandard geo_point field.
